I've had this phone for almost a year now, no problems at all. the T68 was troublesome but the T68i is excellent. I get 14 days stand-by and up to 6.5 hours talk time. It's one of very few phones that you can charge the battery, then go away for a week without taking your charger with you. :o)
A point to remember, the T68i has excellent clarity and volume in use but a weak RF signal. I use Vodafone as my air-time provider, so no problems with drop-out. I tried my wifes "Sim card" in the phone, "T mobile" and did have a few problems of dropped calls.
The calls were excellent in quality while holding the signal, but dropped very easy, even just moving the hand-set slightly would cause this in a weak area. Hope this extra info. is of some help. j.
