i got the unlock info from cingular yesterday for my treo 650
i have not yet tried to unlock it
not sure if i should wait till i get over there, get a sim,
and then proceed
or, just do it now (have no way of varifying if it works or not)
also i am traveling to germany,switzerland,latvia, and lithuania
latvia and lithuania appear to be out as far as prepaid sims go
but they are not cheap in germany and switzerland
plus i am not sure if i can get data with the german sim (i will be there most of the trip)
anyone have any experience with the worldwide prepaid sims?
they seem more cost effective (again i think only sms is provided)

i read the whole thread on unlocking your gsm treo and it was helpful
but if anyone has any more thoughts and or experience on the subject
input would be greatly appreciated!

cheers
