should i do this...

ok so i deleted instagram and tried to download it again, but i didnt have iOS 5. i tried to update it to iOS 6.1.3(im 4.3.3 right now), but it said it will erase everything. i back it up and clicked restore, and it said it wont restore the firmware. does firmware include apps? if it does, is it worth deleting all my apps for instagram? i loved that app, but i dont know if i should do it. i really want to do it, but i have like 5 paid apps. also i have minecraft and scribblenauts, and on minecraft theres a world where ive been spending 1 years on and making it look all nice! i really dont know. i love instagram. i love minecraft. i just feel like i wont be happy either way if firmware includes apps.

You should ask your dad. There's probably a way to save all the data from all the apps.

If you have a apple account, and you updated and don't have all the apps you paid, you still don't have to pay for them again. Like if Minecraft PE got deleted, you can still install it but I'm not sure if it will save the world.

Can't you use iCloud to re-download everything? If you already purchased it with your APPLE account, You'll be able to get it again.

yeah, like the other(s) said, if you paid for an app and you delete it, you can reinstall it without paying another time. not sure if your world will recover when installing minecraft again though.

so... should i do it? because my minecraft world has over 20 floors, a huge swimming pool, a hot tub, 2 waterslides, 4 waterfalls, been to the nether 3 times, full diamond armor, diamond sword, over 2 chests of cobblestone, 30 something diamonds, 1 stack of butter, a lot of iron so i dont know how much, a couch, 2 bathrooms, a huge netherrak building from going to the  nether, a pyramid, a farm, a miner cave, a cobblestone bridge leading to where my house is, my bedroom floor is unfinished im still working on it(its red and yellow checkered), and 2 mushroom farms. i have some other things, but they're not that important.
