Can anyone recommend iphone 4/5/6 repair kits?

I'm looking into repairing iphones for a little extra cash, I live on a university campus and its just crawling with iphone users.

I'd like to be able to fix 4/5/6's and their variants. Cracked screens and other easily repairable issues.

Does anyone have any experience doing this? Where is the best place to get information on it? Can you recommend any good cheap kits that'd allow me to repair multiples phones (not a single replacement).

 

There is a lot on ebay check it out

 

That's way too vague.

 

My friend does a similar business. In reality the only relatively easy repairs are the back cover. This only involves purchases an iPhone screwdriver kit and sliding on a new one
Even replacing the front screen involves you to have knowledge of the complete make up of an iPhone as you have to take it apart replace the screen and reassemble it.
I'd advise you to read up on the components of an iPhone and then buy some cheap back covers, screens,home buttons and microphones

 

I've repaired a few iPhones, mainly only iPhone 3G's and 4's but when it comes to the tools required for repairing you can't really buy stock that will be used over and over again, except if you're wanting to buy the screen pryer suction cap for the screen. Other than that you will be buying alot of the stock mainly for one phone per kit per say.

eBay definately has screen repair kits very cheap, definately depends on what model of iPhone you're repairing though. I used to buy screen kits for iPhone 3G's for about $12, but the kit usually comes with everything you need. Screen cap, and pryer usually come in a screen kit when you purchase it.

As for information on how to repair phones I'd definately look at YouTube videos and search on the internet, before I knew how to repair the screens it took me about 3 hours of research and I repaired my first screen on my own.
