Thanks. Actually, wirelessadvisor.com has confused me even more. It says t-mobile only offers GSM / GPRS. My pearl says that I am using EDGE. ATT shows up as having GSM / GPRS and EDGE. Could T-Mobile be "borrowing" ATT's network in my area?
The reason why this is an issue is that I purchased a cell phone booster for my home for 1900MHZ. wirelessadvisor shows that ATT uses both 1900MHZ and 800MHZ in my area. I wondering if I need to trade my 1900MHZ booster for the more expensive dual 1900MHZ/800MHZ model.
Any ideas?
Thanks,
