there are 2 sms's in my nokia 1100 inbox which wont open or delete.After trying to conventionally delete them, I tried removing sim card and it didnt work,also tried removing battery.
The phone is old but o/wise works well and it does what I need it to do.
You can do a master reset to your Nokia 1100. Doing a master reset would turn your phone to default factory settings. Hence the SMS also will be cleared. You can get a free master reset code for a Nokia 1100 from Unlocking4Free.Com Good luck mate.
