How much does it cost to repair iPhone 4 parts?

I have an iPhone 4 with a desensitised home button (I need to apply extra pressure to get it to respond) and also when I make or receive phone calls, the microphone stops working. No one can hear me.So, how much does it cost for Telstra or someone to repair these 2 issues? Can they do it or am I screwed? Advice please.

Its not as bad as you may think… Actually alot of these repairs can be done by yourself, however most are geeky like me, so believe it or not, but the PC repair places, such as Geek Squad or others alike will do it for a small base fee plus parts…

Run about 20 - 40 dollars, my guess is they'd want at least 1 hr labor, be about 100 total…

Have fun good luck

I think these are small problems, you can replace it yourself, no need to go to repair shop

home button is only 2.5 bucks
