ADDING AN IPHONE 4 TO VERIZON FAMILY PLAN?

Currently, I'm sharing a Verizon Family Plan with 2 other family members. We all have regular, Samsung phones. Nothing fancy. The plan includes unlimited texting and 700 minutes of talk. I want an iPhone 4 but I do not want to increase the rates of the plan. Is there any way I can buy an iPhone 4, add it to the plan without making any changes (not adding a data plan) and keeping the same exact rates we have right now?

Will Verizon replace my iPhone 4?

Well I have had my iPhone 4 not 4s but 4 since November of 2011 i had a different phone for a year with verizon and my contract was due this past November. Still with Verizon. But recently I changed my number to where my sister used to have her line. So now I don't know if I can upgrade. Or can Verizon change it to another iPhone because this one is beginning to mess up. The lock button doesn't work neither does the down volume. And to top it off when I plug it in to charge it doesn't instantly charge I have to mess with it for it to charge and its not the chord because I've tried numerous chords

I'm unable to update some of my iPhone apps. Why?

I've noticed that when I try to update certain apps on my iPhone, the app store will ask me for another user's apple i.d. Password instead of my own. I had this same problem with my previous iPod touch and to my knowledge, I'm the only one who's having this problem.

Can I retrieve photos that were lost during iPhone 4S system restore?

I just got back from NYC and I took over 300 photos with my iPhone 4S. My phone had no service and the guy at the phone place restored it to see if this would solve the issue. I wasn't aware that he would be doing this, so when I got my phone back all the pics/videos everything was gone and my phone is still showing no service. Any suggestions on how I can get these back? My phone is running IOS 6.
