only showing update 1.50-2?

[griff]

i just run a pandora easy installer that claims to install 3.71 m33-2.it all appeared to work fine-the battery creator program runs fine(i haven't actually changed the batt yet as i haven't got the other psp here)but the only other thing showing on the xmb as saved is a 1.50-2 update and a corrupt icon.is this right-or should i be showing a 3.71 m33-2 update?

don't want to run anything if it's not all there

sorry if it's a dopy question-did have a quick look round but couldn't find what will actually show on the psp menu

thank you
