Well i finally got a phone i like! I used to have a Samsung B7300 Omnia Lite Sim Free Mobile Phone - Black
which broke down all the time. The day this phone arrived, I thought 'have I done the right thing getting an S2?' At that moment I had to pull the battery from my old phone, because it glitched. I did the right thing.
This is the best phone EVER! It really is amazing. The app's, the camera, the speaker, everything. A lot of people say the contacts menu is out-dated, and I agreed, untill I updated it to Ice Cream Sanwhitch. Now the contacts menu has changed for the better.
A quick notice. If you got an S2 on a contract where the phone was provided, then updating is down to your provider. If you're like me though, and you got it sim-free, just install Samsung Kies on your PC, hook the phone up using the USB cable, and it should alert you that there's an update. The ICS update makes everything better!
When you finish the update, and have finished applying your back-up files, and setting it back up, follow these instructions.
1: Switch off the phone, and disconnect all cabbles.
2: Remove the rear cover, and take out the battery, sim-card, and SDcard.
3: Wait 60 seconds before putting everything back in, and restarting the phone.
This should allow the phone to reconfigure, and rest properly. Doing this WON'T delete any of your settings. All of your data will be fine.
Again I love this phone so much, and would recommend it to anyone. :]
