If your phone is not lazy, you may be able to go with 0912 build.. if it is.. 0913 (only difference is the kernel is only 710mhz vs 748) me personally i had issues with the newest (0912) but i think my ascend is trying to give me a hint because the only thing that didnt work is i had no sound.. went back to 0728 and it works fine with mms (on metro though after metroff).. i always had issues with mms so i dl'ed apn manager from 81 square from the market.. its free.. make sure the cricket is checked (in your case) and it worked.. htc and iphones mms always came through sporadictly but within the past two months or so they started to be almost flawless.. but still have their moments.. with me making no changes.. its hit or miss sometimes i think.. depending on the provider imho half the time.. anyways.. long story short.. flash cm7..
flash gapps.. reboot.. fill out the initial questions.. reboot after it syncs.. run apn manager, click cricket (sorry if i'm off here i am on metro and it was never checked), reboot again.. give it a little time.. (download a few apps you want, make some coffee, drink a beer, whatever lol).. reboot again.. it needs to settle..
Sidenote.. I've always followed this for flashing.. but i'm on metro and its always been a pain with mms at times... works good though for me now.. hope it helps
