I think Perky69 was just trolling. Mmeh.
Anyways, I did some research and I think I might try something I really wanted some half a year ago, Cyanogenmod. I see that it's now supported as of late last year and fully functional.
Just google Cyanogenmod Mesmerize. Now, if I could only find a solid way to pure 2.3.5+
I'll comeback here and post about my Cyano-experience, and if I find something else close to what I'm looking for.
I had in mind the Aviator for a few days, the itch of jumping to the 4G train had me almost waist my now available-by-points upgrade. But not anymore and I am just gonna wait, I think I rather get the SGSII than the Aviator. If only SGSII was 4G and/or GSM.
Will be making a new thread (if there's non) for the Cyanogenmod posts.
