Hi, I am new to the iPhone and new to the forum. So please bare with me here. Have questions about replacing the battery in case the battery drains out and cannot hold a charge anymore. I bought this unlocked iPhone from a local GSM shop from Europe and I know that Apple can indeed replace the battery for $79. No big deal. I just want my iPhone battery to be replaced. Period. 1. If I bought my phone from a non-Apple shop (GSM Shop from Europe), will Apple or any Apple authorized service center can still replace the battery? Or, will Apple replace the battery only for phones which are bought only from an Apple store? 2. If I take it to Apple or any Apple authorized service center, will they have to ship my phone somewhere else in order to change the battery? Or, can they do it locally there? 3. What if I want to keep my original phone after a battery replacement? Can I ask them to replace the battery and then keep my phone or will they give me a new replacement phone? I had been to Apple's site on battery services, but I still need a bit of guidance here. Thx in advance!
