This phone is rumoured to have slightly less reception than others. I have had absolutely no dramas with mine at all and I've had it since March. Are these phones network locked? That's what I'd like to know.
Barneyfife, the only differences between the T68m and T68i are the casing, keypad lights and software. Sonyericsson have offered a free software upgrade for the T68m to give it all of the functionality of the T68i, including using the communicam. Both phones will use the MCA-10, but the MCA-20 will only work with the T68i. I have yet to try the camera in mine, prices around here are way too high for them.
The software upgrade should only take about a half an hour, but I had to send mine away and apparently only one tech had a clue what to do so it took a week until I got it back. The software upgrade really makes a huge difference. The MMS is really cool, I just need to find people to send MMS messages since I get it free until October 1st.
mwdelta must have had a lemon. You get that with all models. Nokias are notorious for their problems (screen fade in several models, liquid ingress in 82xxs from faulty construction, software lockups on the 33xx series, the list goes on).
