As i reported earlier there is some people that has got the new 3G MicroCell device and at the moment you can only get it in Charlotte, North Carolina and one of those people has got a full review of this new device and by reading it through you will notice that this piece of hardware actually improve from a 1 bar edge connection to a 5 bar 3G connection.
According to the reviewer the install was pretty easy so it didn’t take long before he got it up and running.
So check out this great full review by following the link further down

AT&T released their new 3G MicroCell yesterday in the Charlotte test market.  Hey!  That’s where I live!  I’ve been waiting on this device for a while.  Ask anyone I work with how my cell coverage is at home and you’ll find out it’s abysmal.  Calls are short, frustrating, and futile.  For once I won’t blame AT&T for this.  I live in a low area in my neighborhood and both GSM and CDMA coverage is very bad.  I tried a repeater when the iPhone first shipped with very limited success.  The 3GS iPhone appears better but many times I’ll get a “You have a new voicemail!” notice when my phone never rang.  Frustrating.
