Hi, I have a Nokia 3595 GSM phone that uses SunCom (AT&T). I just moved into a new place and I can only get reception in certain parts of the house. This is really annoying me. I used to have an external antenna for an old Panasonic phone I had, but I've searched on Google and can't find a similar antenna for this phone. So I had another idea . . . are there antennas available which act as repeaters. For instace, could I buy an antenna that would be in my attic or on my roof which would then act as a repeater and/or amplifier so I could get signal throughout the house? Also, what frequency band does the AT&T (now Cingular) GSM network use?
