My Mini Pro is sitting on my desk next to my old Treo 650. They are both on the same network, T-Mobile UK, but the Mini pro shows no signal while the Treo shows 5 bars, ie a full strength signal. If I power down the Mini Pro and then power up it will show a signal for about 10 minutes and then loses it. The only way I can get a signal is to power down and up again. Any ideas anyone?
