I have no use for a touch screen cellphone. i went to T-Mobile and looked at all their phones and to choose the correct one for me. all of us are different, so your choice may competely different than mine.
I chose the Sony Ericsson flip phone in aqua green color. its perfect for me. since i wear hearing aids, the phone has a great feature for the hearing impaired. my wife has a Samsung Behold touchphone and wishes now that had chosen one just like mine.
I love this phone and i hope you at least give it a try at T-Mobile.
