Why is my iPhone 4 messed up?

There, my iphone4 is only a year old and I got it brand new. It will connect to my Wi-Fi and then 30 seconds later the Internet won't work. It still says I have Wi-Fi on but it won't load and it has nothing to do with my connection because my iMac, laptop, ps3, and Xbox all connect perfect to it. And another thing. My iMessage is so messed. I'll send my friends who have iMessage and they all have iOS 6.0.1 a message and it says it sent and a phew minutes later ill giro the message an it will say sent as text. Even though when I sent it, it was blue. This happens a lot. And I've tried restoring my phone. I've rest the networks. I've rest my Wi-Fi. But nothing works. I have dropped my phone quite a bit but this has never happens before so I'm not guessing it has to do with anything on the j side. But it mite. And I mite cancel my phone and get a new one cuz it does has a cracked screen and should I get an iPhone 5 or galaxy s3?

Since you've dropped it a lot, you may have damaged the Wi-Fi antenna, causing it to be unable to maintain a signal. As for iMessage, that's not just you.iMessage has had a lot of problems lately for everyone, including myself. As for the iPhone 5 vs the Galaxy S3, it's all preference. I've used every mobile platform, and personally prefer Android, I'm just using a friend's old iPhone 4 right now because my Droid X is having some hardcore issues. The S3 and the iPhone 5 are both amazing phones, but if you're used to iOS and have never used Android, I'd stick with the iPhone 5 just because a lot of people who start off using iOS find it difficult to enjoy using other operating systems. Also note that the Galaxy S3 has a much larger screen; the iPhone 5 has a 4" screen, whereas the S3 has a 4.8" screen, so keep in mind how big it really is. I would go to the store of your carrier and play with them both for a little while and see which one you prefer, but I can tell you now you'll probably prefer the iPhone 5 if you've never used Android before.
