the T68i experience
Yes, the t68i is a GSM phone, and it has a changeable SIM card.
I just bought one to replace an older Ericsson flip-phone.
Hands down, the sound quality of this phone is superior to anything I've heard. You can hear everything, and it's as if the person were in the car/room with you. Great.
I don't know whether it's AT&T or Ericsson or what, but I have always suffered from dropped calls out the azz (last phone was dual-band); unfortunately, this phone appears to be no better at keeping a connection - it may actually be somewhat worse in some parts of town (I live in LA).
The color display and joystick are nifty for the gadgeteers out there, but pretty damn useless on a phone, unless you're willing to pay up to 3 cents per kilobyte (from AT&T) to transfer (send/receive) data. That is nonsensical.
I miss my old phone's simpler operation - the T68i requires several more steps through layers of menus to complete some of the tasks that seemed closer to the surface on my older phone. Of course, this may be inexperience talking, and once I get up to speed on this thing (not much of a telephone talker am I) I may swear that it's the quickest, easiest thing to do since learning to pee standing up.
There's my two bits in response to your request for user comments! regards,
