So I'm still using 3.0 on my launch-day 3GS. Long story short I'm pretty busy with travel and everytime I am home and want to upgrade and re-JB I find out Apple has JUST released a new FW and it's "not safe" to update yet, for JB sake anyway. Curiously enough, I'm home now and sit down to do it and the firstthi g I see on the Dev-Team blog is that 4.2.1 FW was just released, so it's literally EVERY SINGLE TIME lol. Anyway, my issue is my phone performs like crap. It crashes constantly (either Safari or the actual FW, rebooting the phone into safe mode) at random times (multiple times a day), and eerytime I try to do updates from the App Store it also reboots into safe mode (automatically). It also takes FOREVER to boot back up now (this just started happening last week while I was on a business trip). It will turn itself off and just stay on the apple logo for a good few minutes, then just a black screen (but a LIT back screen, not like a locked black screen) for a few more, then it finally boots. So I NEED to do something about it. Plus most of the cool new apps/games are for at LEAST 3.1 or later so Im missing out on a bunch of good stuff. I read that for OLDER 3GS phones it is safe to go to 4.2.1 and JB untethered, and since mine is a launch-day phone still on 3.0 FW I'm pretty sure it qualifies as "older" lol. So I'm just looking for step by step directions (or a link to such) on exactly how I go about the process of upgrading to 4.2.1 and jailbreaking it. Dev-Team's blog lists a few different methods, none of which I'm familiar with (I used PurpleRa1n RC2 to JB, couldn't have been simpler lol). I'm not tech/computer illiterate, so I don't need baby-step instructions, I'm just looking for clear instructions as the only JB method I've ever used was the PurpleRa1n one. Specs: 3GS (launch day) 3.0 FW PurpleRa1n RC2 JB Windows XP PC Not sure which iTunes version, but it's old, whatever one came out around the time the 3GS did because I ddnt use iTunes before that and haven't updated since (I remember awhile back this forum and the Dev Team were saying NOT to update iTunes for JB-sake). Sorry for lengthy post, just trying to get all details out from the get-go so I can get the process started ASAP, phone is driving me nuts and becoming unusable. Thanks in advance for any help/info.
