I recently cracked my iphone 4's screen. I took it to apple and the cost to replace it is the usual $200. I was thinking that I may be able to fix it myself for less money. My question is, where should I buy the digitizer from? Is the digitizer separate-able from the lcd or are they fused so that I would need to by an entire lcd+digitizer combo? Does anyone have any feedback on the repair process and its difficulty? I watch a couple videos and read the ifixit tutorial guide. The process seems pretty long but is it difficult? It seems easier than an ipod since the iphone has screws rather than only glue.
