Lost apps w/ new radio board

[dharsh06]

I just swapped a verizon pixi plus to my sprint pixi. The wifi works great and all that. i backed everything up before i did it, however i lost Angry Birds and a College Algebra app and i go to get them back at the app store and they are lost. i sent a link from this website to my phone via sms and it says these apps are not available for my model. is there something i can do via preware? any help at all.. also, when i plug my phone in via usb to my computer i no longer have the option to sync media.. are these things i just have to deal with. also is there a patch to "hide the verizon nav" any and all answers or suggestions would be greatly appreciated!
