Hey guys!! don't worry; this is not one of those questions that ask about ip4 unlock or anything like that. I have ip4 BB 2.10.04 and I jailbroken it. I have a few questions. 1st. It shows that there a 1 on my Cydia which is an upgrade, so when I went to Cydia->Changes and it shows that there's 1 thing to upgrade; should I upgrade it? Will this upgrade my BB to 3.10.04 which is 4.2? 2nd. When I try to download some games/apps through Cydia, there's a warning in red that said "iSO4.2 Update Warning/Click Here To Read More. So if I download the games/apps, will this upgrade my BB to 3.10.04 which is 4.2? 3rd. I've saved me shsh files, so if accident which is whatever happen and upgraded to 4.2 will I be able to downgrade the BB also? Thanks ^^ been waiting for a period of time for the unlock for 2.10.04 and knowing that it's coming out soon; so I dont want to do anything above like Q1 and Q2. So please, transfer me some of your knowledge. Thank you!
