* Tips for Universal-SIM iPhone 3G v2.2.1 software users:
1. Reboot the mobile phone after each unsuccessful try.
2. Wait until phone displays “No SIM card installed” or similar message in other languages then you can insert your simcard together with Universal-SIM. Do no insert universal-SIM before iPhone 3G software had finished loading.
3. After you insert the simcard phone must display
00:00 - “No Service” -> (after about 20 seconds) 00:20 -”Searching…” -> 01:00 “No SIM card installed” -> 01:30 wait and get signal -> 02:40 -> “Searching…” -> 03:40 - You can use the phone!
The times are approximate and will depend on the speed of the simcard and settings used ( please use normal 10k baudrate ( not higher )!
