Ok so I had an idol half hour earlier today. I had a look in the 'Big FAQ' and found the themes.zip to load additional themes on your Blackberry.
I'm in the UK and have a 7290 badged up as T-Mobile.
Trouble is, I tried the themes, didn't really like them and thus removed them using application loader. Problem is it seems to have overwritten the default theme on my unit, when I removed them, it went to a black and white, incredibly basic (and completely awful) theme. The nearest I can get to the original (which was the default 7290 small icons I think) is by loading the themes back on, selecting the small icons 7290 theme, but it doesn't display properly, the fonts for the network provider, GPRS single indicator etc are wrong...but the icons are correct.
If I take the battery out and leave it for 24 hours will it loose these new themes and revert to the out-of-the-box theme?
