Hello folks,

I am using a unlocked 680 on T-mobile network and I occasionally get phone freeze on pick up (maybe 1-2/per week, not too bad); what bugs me more is the SMS freezes/lags where after you send an SMS the phone freezes for 20 to 40 sec returning to normal afterwards (I think this is a known issue with T-mobile and 680).

I am using an old T-mobile SIM (2001, I think) and I have read some suggestions that you may eliminate/decrease the above mentioned issues by changing to a new SIM. T-mobile charges $20 for a new SIM, so I was wondering if anyone has any experience with this upgrade before I drop my 20.

Thanks in advance.
