I have just finished charging my phone all of a sudden the touch screen at the bottom has become unresponsive where you can put 4 icons and the manu button. I can not get into my contacts or make phone calls. However i have set a few shortcuts on the screen with the buttons and its the same for the keyboard the space at the bottom does not work.
I have cleared data so far and its not done the trick switched on and off a few times and still no joy.
Anyhow i am in England im guessing i need to send it away.

try to reboot your phone, if that doesn't do it, then try a taskiller

if that doesn't do it then use Update Service to repair your phone
Make sure you backup everything before using PCC or Update Service
You can install Backup & Restore (works for arc, play, neo, x10, etc)

just to play it safe sync your contacts w/ google if you haven't already
if you don't want to use the backup & restore app then
Install "backup SMS" to back up your SMS and MMS to your Gmail

or your SMS use
"backup & restore SMS"
https://market.android.com/details?id=com.riteshsahu.SMSBackupRestore&feature=search_result
or for your MMS use "Save MMS"
https://market.android.com/details?id=com.schwimmer.android.mmsextract&feature=search_result
one last thing
Don't worry so much about backing up your apps
on your computer go to
market.android.com -> log in -> click on My Library -> and send all your apps to your phone
no problem
