Just to expand and clear a bit about versions, see Nabi's list here (it is often updated):
-iGO-8-Amigo-and-Primo-releasesBasically, (and it can be a little confusing), "9" started the Primo branch (after which further development of the iGo "8" versions ceased),
with 1.2 being pretty solid --AKA Primo
9.2.xxx After a long delay Primo "2.0" finally came to be with final versions in the
9.6.5.xxx range.
Now comes the latest (often referred to as Primo "2.4" which puts it in line numerically with the iPhone version)...
9.6.13.xxx.
One could say that each subsequent version had increased demands on resources to utilize any of the newest features. In general, a device should have 128 MB Ram and a decent processor with at least 480x272 resolution to take advantage of the newest versions.
As FBF said, it appears your device is of this class, so feel free to give any a go that might be an upgrade from what you have. Always back up in case you don't like a newer version for any reason, and you can easily revert to what it was.
