Forgot Passcode for iPhone 4?

I got a iPhone 4 Yesterday for my grandfather and he has forgotten the pass code for the lock, he says he doesn't have a USB to connect to iTunes and Sync and Restore it. This is really awkward so I'm just wondering if you can tell me how to wipe the phone without using iTunes.

Can I activate a iPhone 5 that wasn't bought at AT&T?

Ok I have a iPhone 4 with AT&T and was about to buy a iPhone 5 off someone who is with AT&T also. If I was to buy it what would I need to get it activated? Note: I know iPhone 4 SIM cards are different from the mini SIM cards in iPhone 5 sim slots. Would I need to take the iPhone 5 to AT&T for them to give me a new SIM card for it & will it cost me? Or will it cost me anything to get this iPhone 5 working on AT&T. It is a AT&T iPhone 5 also. Or would they not activate it since I didn't buy it from Apple Retail Store or them.

IPhone 5 GB usage is almost full even with few things on my phone?

I've had my iPhone for a little over a few months and I'm wondering why I have very little storage space available. Only over a few GB's. I have the the 16 GB iPhone 5 and have litterally NO songs, just a total of 12 basic apps, none use up more than 1 GB. I've deleted all of my message conversations. I have 20 Notes… Ill just say this, I don't have much on my phone at all. But my buddy has a 16 GB iPhone 4 with over 200 songs, way more apps then me. The same amount of pics and videos (and no my videos aren't long videos, just a few couple minute videos) and He still has FIVE WHOLE GB's of storage space available. Does anyone know why this is? Why doesn't my iPhone have that much space left to use even though I don't have much on my phone? When I saw my buddy had like 4 pages of apps I was like "WHAT? HOW you GET All THEM APPS" I barely have one page of apps.

Iphone 4 unlimited talk, text, web for $30, does it exist?

I just got an iphone 4 from someone and am looking for a cheap iphone pre-paid plan. I'm looking for pre-paid only. Are there any plans that offer unlimited talk, text, and web for $30.

I know Vergin has a $30 unlimited text and web plan, but it only has 300 talk min. I need everything, including talk unlimited. My mother calls and keeps me on the phone for at least 1 hr.daily, so I need unlimited talk as well. I also know that straight talk has unlimited talk, text, and web for $45 a month, but you would also have to get a sim card for $15 and $45 still seems a bit high to me. I know that is way cheap compared to most iphone plans though.

Is there any such thing as a $30 unlimited talk, text, and web pre-paid plan for an iphone? I have already done a google search without any luck. Everything that has unlimited for this price either doesn't do iphone or has only text and web unlimited and like 300 min. I would go through that in like 5 days just from talking to my mother alone.So, unlimited is a must. Any options out there?
