iPhone 4S Lock button Issue

Hello,

I have checked several threads about this issue and I have only seen that the Apple Store can replace it for $199 if the warranty is expired. I was wondering if there was anyway to fix the issue as opposed to buying a whole new replacement phone?

To be honest, I don't really care for the iPhone and don't want to purchase one again. The other reason is I absolutely can not afford to replace it.

I have turned on the Assistive Touch feature and it's been working fine, but a little bit inconvenient. Is that my best bet?

Thanks!
