Skype on Three

If you put a 3 SIM card into a 3G* mobile from another network you can still make calls, send messages and access the internet, but you can't access Skype.

We’re working hard to fix this. Our aim is that over the next few months customers will be able to insert their 3 SIM card into any popular unlocked 3G mobile and automatically get the right settings for the 3 network. Plus you’ll also receive a link to download the correct version of Skype on 3 – so you can have free Skype-to-Skype minutes forever.

It is important to note that the Skype mobile client must be the version which comes directly from 3 (rather than any other source) in order to be able to get free Skype-to-Skype calls forever.

Skype is available on a huge range of our mobile phones including Nokia, Sony Ericsson, LG, Samsung, and the 2009 Global Mobile Awards Mobile Phone of the Year, the INQ1. Check if your 3 mobile is compatible with Skype here by entering your phone make and model.

How to restore Original ROM on XDA Minis

http://forum.xda-developers.com/showthread.php?t=342744

1. Download SoftSPL by the-equinoxe.
2. Download the IPL/SPL based on your device and carrier(attached below)
3. Extract SoftSPL to its own folder and then extract the nk.nbf file from the correct IPL/SPL to the SoftSPL folder.
4. Run Start-sSPL.exe and follow the simple directions. It is almost fully automated(your screen will turn white during the flashing process and it will appear to have crashed. This is normal so just proceed like normal)
5. HardSPL should now be removed if everything worked properly. Depending on your device and Carrier, download the appropriate Rom for your device:
