Upgrade jailbroken Iphone 4

[jondoe98]

Although Ive done alot of research on this topic, I still have alot of questions that I cant seem to find an answer to.

I have a jailbroken Iphone 4 thats running 4.1 and I want to upgrade to IOS 5 (or any stable version). My version is running fine but there are a few apps that i cant install because of my 4.1 version.

I keep hearing the word "baseband" and I'm not sure what it means or how it pertains to me.

My questions are:
1. How can I upgrade my Iphone 4 (v4.1) to v5?
2. Will i still have all of my jailbroken apps intact as I do now.
3. Is it pretty straight forward in regards to how to upgrade.
4. Is there anyway to backup my phone in case it fails i can revert back to how I have it now?

1. if you don't have shsh blobs then you have to upgrade to 5.0.1
2. get pkgbackup to backup and rebuild jb apps paid app but worth it. just makesure they work with 5.0 and 5.0.1
3. yes IClarified has tutorials
4, Yes Itunes tinyumbrella to save shsh blobs

Baseband is in the general about you want 1.59 baseband even if you don't unlock it makes you device worth more and can be preserved redsn0w or sn0wbreeze.
