Flashing Verizon iphone 4 to cricket?

I'm pretty sure i was able to flash my iphone 4 over to cricket
when i look at the settings, the service no longer says "Verizon Wireless" and now it says cricket but
it won't let me make any calls at all though, not even customer service or anything.

What's the next step? I have never had a cricket account. Do i have to have the phone activated by cricket FIRST?

My iPhone keeps asking me for my apple I. D password?

I changed my apple Id and password. Whenever I go to the App Store from my iPhone it asks for my new password to my new apple id which is good. But at random times when I'm texting or something, the old Id will pop up and asks me to type in my password. I don't know how to fix this but it's driving me crazy. :/

Clean iPhone 4 or Scratched iPhone 4S?

So, I can either choose a clean iPhone 4 (no wear marks, no scratches, but home button needs to be pressed heavily or won't work only some of the time). Or, I can choose an iPhone 4S that has a lot of small scratches all over the screen and surroundings, and two big scratches on the back. Both are 16 GB. I know the iPhone 4S is faster, but I really get annoyed by the small scratches. The iPhone 4 looks almost new, but the 4S looks like it had been dropped sometimes. Oh, and one more thing, If i put a screen protector over the 4S, will I still be able to see the scratches even with the screen protector on? I don't know. I'll leave it up to you guys.

How to disable album artwork on an iPhone (NOT remove)?

Yes, I know how to use Get Info and delete the artwork. But I don't want to delete it, I still want it to show up in iTunes when I use my computer. I remember in the past using an option on my iPod nano that allowed me to sync songs WITHOUT copying the art, in order to save space. Is there a similar option on the iPhone 4/ in iTunes 10, or has this setting gone defunct? (If so, we should really get Apple to bring it back, that was pretty useful)

How to change Wi-Fi password?

I have a linksys router and have little to no clue on how to change the password. The current password is the preset one with the 30 or so different letters. So long as this is set as my password I have no way of connecting my iPhone or iPod. I don't have an Ethernet cord that will connect my router to the computer to access the routers web-based set-up page. Also, I'm not exactly the most "Techy" person ever so even if the answer could be simplified it would be greatly appreciated.
