My phone is on its deathbed ..... again (update)

So, Now that my phone was unbricked about a week ago, There's something wrong - again.

When I open the Camera app, all it shows is a black screen (but I can still press home button to exit)

I went to the same repair store as before, and they said that it has a broken camera module, It is a hardware problem.

Replacement costs $19, And we are saving up for a new car (budget is $2,500) so we cant have it repaired.

Also, the silver metal rim around my phone has scratches, and now, battery is weak.

Conclusion: My phone is on its deathbed ..... again.

Update log:

Oct.18.12: Play Store does not update, Phone gets slower when on Wifi(all apps)
