I recently bought a brand new SL 65 GSM phone for use with T-Mobile. After charging it, putting in the Sim card etc... the phone stalls out displaying "please wait" on the screen. This will stay locked until the battery is taken out-I can't even turn the phone off other than removing the battery! I am likely going to return it, just wondering if anyone else has experienced and whether I should try another SL 65 or switch to another phone. Please help!!
