iphone app instalation

[swedge]

ive downloaded a couple ipa files (GTA3 and batman)

how do i actually install them?

Add the file to iTunes Media/Mobile Applications

Itunes 'should' see it and let you sync. OR just 'add to library'

hmm when i open the file it adds it to the apps bit on itunes but when i try to add it it says are you sure you want to remove the other apps, how do i make it leave the current apps and only add the new ones

[swedge]

i had to right click my iphone and transfer purchaces first
