BBHub reader Benjamin writes that he just got a Nextel BlackBerry 7520 from a friend.

Benjamin has tried to unlock it, but has not been successful to date.

"I read on the Web that (the 7520) can't be unlocked to operate on (a) GSM network," Benjamin writes. "What about CDMA?"

He hopes that in an implied best-case scenario, it is possible to do both.

Having never been in that position myself, I hand this one off to the assembled multitude of eyeballs that are currently gracing my virtual presence by reading this post.

Well, BBHub readers, have any of you unlocked a BlackBerry 7520? What are your experiences, and advice, if any, for your fellow BBHub reader?

BBHub reader Scott Kane is not able to come up with an explanation of why a series of BlackBerrys he has used all seem to totally lose their Bluetooth connection in his automobiles.

"I have had problems with the 7100, 7105, 7290, 8700, and now 8100 all dropping my Bluetooth connection in my car," Scott tells us.

He adds that his vehicle has a U-Connect from DaimlerChrysler factory installed. Not only has it been happening in five different cars and five different BlackBerrys.

By now, the first indications of a failure are familiar to Scott. He says that while the BlackBerry Bluetooth connection is fine and reliable at first, then before long then the BlackBerry starts showing "connection to U-Connect lost."

Removing the battery and then placing it back in provides temporary relief. But do you agree with Scott and me that constantly having to do this is a pain?

"At first I thought it to be the car," he writes. "But now that I've been through 3 cars and countless BlackBerry devices I think the problem lies in the BlackBerry."

Readers, have you had similar experiences?

Early this morning a friend emailed me this question:

If you are using an internet (IMAP) account along with BIS (BlackBerry Internet Service), do the messages deleted or marked read or replied get marked read/replied or deleted back to the original IMAP server?

Say for example, would "Read" mail be marked as read/replied or deleted on the BlackBerry. My friend said he wanted to know because it would help him make his purchase decision.

Well, we have some answers.

We haven't had a bad couple of weeks at BBHub. We've been among the first- and in some cases, the first- to bring you details and photos of the BlackBerry 8100 Pearl- specs, pix (outside and inside) and release dates. We've also broken some news about exciting patents that point to some added functionality in current as well as forthcoming BlackBerry devices.

When it comes to major news, we haven't missed a beat. OK, maybe one or two.but hopefully nothing major.

But as you have been noticing our never-ceasing dedication to important BlackBerry news, you may have been picking up on the fact that posting has been a bit light here of late.

To that, I take you into my world of personal relocation from one residence to another. If you have ever been there, I am sure you are well aware of the many demands on time, as well as the pure logistics of getting the move to go smoothly. Tape measures, packing boxes, utility-related arrangements (and a now-solved glitch or three with that).

And for those of you who care to understand, sometimes relocates are not devoid of interpersonal dynamics.

I'm now in my new abode- and in conjunction with the move, I am migrating more than 140 gigabytes of files from my old PC to a new one I have just bought. These moves can involve glitches and workarounds- thanks to my BlackBerry I have been able to stay in touch with our readers.

Me and my techs assure me everything will be cool PC-migration-wise by the end of this week. At that point, it will be full speed ahead with the many, topically varied diet of posts you have come to expect from me each day.

But that's not all, readers. I have been in conversations with some additional BBHub blogger candidates- some whom you will instantly recognize. When we staff up, we'll be adding additional features such as BlackBerry device and software reviews, as well as more problem-solving tips.

Can't wait for you to see what we'll be doing here. Meanwhile, the summer is starting to go- work hard, play hard (but responsibly)!

I've been doing the vision thing lately, thinking of additional features we could add to BBHub. In coming weeks, we will be developing ways to convert those visions into reality.

This Hub's for you, so feed me ideas! More third-party software reviews, tech advice, BlackBerry advice reviews, podcasts, etc?

Rock out and feed me some ideas!

On the Yahoo! BlackBerry Users Group Forum Member destroyether2002 (cool name, no?) posted a message titled "BlackBerry 7290: Accuweather Problem."

Seems that destroyether2002 downloaded the Accuweather weather service to his BlackBerry from a site he referred to as "BlackBerry extras." But ever since he installed the free Accuweather, gets a "-1" symbol at the top of his BlackBerry screen. He even de-installed the utility, but the symbol is still there.

Forum Member Chip Brady responded, asking destroyether2002 for the exact URL of the site he downloaded Accuweather from. Then, Chip added this note:

"I haven't seen this (site)," he wrote, "and the ever up-to-date BB Hub hasn't done a review of it either."

Well, Chip, thanks. The way to a blogger's feed is through flattery.

Thus, feeling honored and duly bound, I "Googled" "BlackBerry Extras," Didn't come up with anything relevant to the issue.

But then I had an idea: I went to AvantGo, which does offer a free, downloadable version of Accuweather's software, and typed in the term BlackBerry into the AvantGo User Support page main Search Text box.

I then was presented with a AccuWeather-How do I use this channel? link. Clicked to an explanatory article about this issue.

Not sure answered the question directly, but I've included this link directly below this post.

Frank Stone writes us from Iraq, where he is currently on temporarily assignment.

Well-traveled in the Middle East, Europe, and the U.S., Frank has  been experiencing some signficant service gaps in his T-Mobile BlackBerry coverage. If any of you readers can help shed some light on the problem and perhaps even offer a solution, it would be appreciated.

Frank says that he obtained good coverage last year in France, Germany, Italy and Israel, but now, he is unable to get coverage in Kuwait or Iraq.

He wonders if the location is to blame for his lack of coverage, is there a setting he needs to change.

"I have strong signal (5 bars,) but can't get past 'GSM" which means I can neither send or receive," he writes. He's already tried sending the registration message and performing a network scan.

If any BlackBerry users currently or recently in Iraq or Kuwait have any suggestions, for Frank, it would be deeply appreciated.

Just a little while ago, I got an email from Cingular Wireless subscriber, BlackBerry 7280-wielding and BBHub-reading (bless you, my son) Curtiss Petersen.

Rather than answer his question directly, I thought that I would kick it out to the broader circle for discussion. That means y'all.
