Restore wont restore my instagram,remote and twitter apps
I have a iphone 3g 8 gig on ios 4.2, it crashed yesterday so i tried to do a restore from a backup file that i made which worked it restored all my settings photos and apps except for the twitter, instagram and remote apps for some reason itunes wont restore these back to my iPhone it gives me a error saying that these apps are not supported for my version of ios, but the version of the apps that are synced with itunes are the "older" versions of the apps that are compatible with ios 4.2.
The other thing i wanted help with was if i restore my iphone and set it up as a new device through itunes instead of restoring from a backup will this allow these three apps to be synced to my iphone?
Please i need a solution ASAP as i use these apps for my work
Thank You
iPhone 3G, iOS 4.2
