Basically exactly what the title says... I'm sort of stuck on what to do and I don't have anything to SSH on my phone... only Iphonebrowser... is there any way to manually download cydia or am I going to have to re-jailbreak my whole phone and start new? Any help would be greatly appreciated and most helpful in a step by step manner because I am sort of slow.

Also, for bonus points what APN settings should I be using for mms. I'm on t-mo and the works for the cellular data, but my MMS isn't working... I obviously can't download anything from cydia because its crashing, but if I could enter it in manually that'd be awesome!
