Loss setting for scenes, wall paper, widgets since sim card swap. Can I restore these from backup on SD?

Hi guys! New on here but I have some teething problems with my Desire. This one is about changing from old Tmobile SIM to new Orange SIM after Pac code transfer today. I thought it'd be simples as I've been keeping new orange sim in old phone since contract started while I gave my stupid 30 days paid notice to Tmobile and used better data allowance on Tmobile in Desire. Today I thought it best to do pac change before I forget but on placing Orange SIm in desire it told me I had to lose my settings cos it was a new sim and the old settings were on old sim. I tried ignoring message but couldn't get a signal on phone so figured you must have to accept this reset to make it work. Now i've lost all my carefully personalised settings and want them back! I thought they were being backed up to SD card in settings, privacy but there is no option to restore from there, only back up?! Please can anyone save me having to re-personalise?

Hate to be the one to tell ya this... but you are going to have to redo all the personalized settings like wallpaper, scenes etc I had to get a replacement Eris do to battery problems and went though the same thing.

But hey.. that's half the fun of an Android Phone

Sorry to hear about your problems with all the work, but I think Jay is right in that you are going to have to re-do everything. You make it sound like a big deal, so I'm assuming that you had the phone plastered with skins and what-not? I hope it goes quickly for you.
