Im pretty much having the ssme problem. I had to completly reset my (cricket) samsung indulge
(stuck on samsung screen) and assumed since the mybackup app
came with the fone when i bought it that it would still be there. well it isnt. i have tried everything. looked it the (cricket) "storefront" app
for it, no where to be found. I tried the "myaccount" app
and the "cricketmobilebrowser"
(they have same stuff just a couple more options when trying to search) but that didnt work either. and it is no where to be found in the androidmarket/googleplaystore
I went to mycricket.com read all the tech support stuff no help there. i called 1800cricket told them my problem the guy kept telling me to go to the "cricket clicks" app
or "look under "games& apps
...the under 'cool apps'
to find it" which is not nor has ever been on my fone; not b4 the gingerbread upgrade, not when i purchased it, it was never there. im sure he just thought i was an idiot and couldnt find it.
(i calld samsung when i had reset it)---> anyway he then asks me if they had me call this#-->(228) after they had me reset my fone. they hadnt told me that so guy said i needed to call it to get the fone activated again, i did that even tho it was workn b4 and made no difference after.
i called cricket support back let them know i still cant find the damn app. SO SORRY I HAD TO DRAG THIS OUT SO LONG
(just wish i could have found something this detailed when i was searching around for solutions so that i didnt have to go thru all that mess) ---->SOLUTION<---->->-> APARENTLY you have to go to an official cricket store and have them reinstall the app for you.
im headed the tomorrow since this seems to b my last and only option
i will update if while im there im informed of an easier way or if i discover one in the mean time
again sorry to drag this on
hope this helps
