I guess i was read this late, maybe AE has patched it or just iap crack not working for ios 7
So i decided to upgrade iap crack to iapfree. And it work. Just follow these step
1. Add source sinfuliphone (i cant post link) to get iapfree with core plugin if you on ios 7 same as me
2. Go in battlegem (wifi still on) select upgrade
3. Now, there will be a board that said founder thingy. Still keep that board, you quickly turn off wifi, or if you in ios 7 you can just swipe up and turn off
4.tap buy it, it will said you have buy it like when you open wifi (but no stuff) and just tap continued. If you see "link to AQW" thats mean you succeed (i dont recommended link it if you dont like to get banned. Still, need someone test if that work)
5.go in your inventory, equip all that stuff and now, open wifi or not is your choice, since now you are a FOUNDER (well, at some point)
Thats all, i got it working by doing that and i like to share it with you guys, late 1 month huh?
Btw, sorry for my bad english.
