Few questions before upgrading to 5.0

[Icyrock]

Hi all.

I currently have a iPhone 4, on 4.2.1 I had it when i was working in Sweden, when i came back to England i brought a "GeveySim" and that has worked since .

I am thinking about upgrading to 5.0 and was just wondering if its possible to still use the gevey sim and jailbreak

Thanks in advance

yep, use redsn0w to create yourself a custom firmware of 5.0.1 to preserve your baseband and go from there
