My uncle gave me this iPhone 3G because he got the latest one. I absolutely have no experience with any Apple product, my previous mobile phone was an old, cheap Nokia phone. I'm not the guy who buys high-end phones, I'm already satisfied with cheap, working phone but this iPhone was free, so of course I accepted it. It's an iPhone 3G with 4.2.1/06.15.00 update and it was previously 4.1. When my uncle gave me this phone, the wi-fi wasn't working, it doesn't detect any wi-fi within the area, so I thought updating it to higher version will fix its problems but I just made a huge mess. Here's the story: When I tried to update it on iTunes, I always get an error and I was stuck on a recovery loop. So I saw a solution on YouTube, and restored this iPhone using redsnow and a custom 4.2.1 firmware that I got from Piratebay. But I just made a huge mess, I can't activate the iPhone because I don't have an AT&T sim card, and I live in Philippines and we only have Globe, Smart, Sun carrier here. How can I activate this iPhone? So sad I can't use it now I saw a solution where I can unlock it using this whitedoor thingy. They said I need to downgrade this iPhone and install whitedoor, but when I try to restore it using lower version, I always get an error (1611) before it finish and it left my iPhone much more useless (blank black screen). I followed the instruction using redsnow (I checked Install Cydia, and downgrade option) but I always get the 1611 error when I try to restore it using lower version. Please help me.
