Can anyone recommend a micro-cel device for Blackberry on T-Mobile? These devices are like a repeater that amplifies the cel signal.

I've been using one for Verizon, and it works well. I live/work in a signal fringe area, and my Blackberry 9900 needs some help!

Thanks -

Depending on your service provider, ATT offers one that works on an internet connection via DSL or their other data services.
It work anywhere and sends and receives calls and other data via the internet connection. I use one.
I would call T-Mobile and see if they offer something like Verizon or ATT has.
