You are going to need a custom 4.2.1 to be able to get to 4.2.1 now that you have the iPad baseband....

I've had this exact issue. I had to reboot and reinstall everytime I have turned off my i4.
12-01-2010, 10:04 AM #105Same problem
I try to reset the mnetwork settings and turn off 3g but still the same, i get a signal for a minute and then no service.
Does anyone know about this or probably is a phone defect. I have another iphone and i get great reception with the same sim card

Problem with no carrier after ultrasn0w solved:
iPhone 3GS old bootrom
Updated to Stock Firmware 4.2.1 with bb 05.15
Jailbreak with redsn0w with iPad baseband 06.15
but never got a carrier.
After trial and error jailbreakng about 50 times in any which way you could imagine
I have finally found out that I have a "tethered lock" meaning if I boot my phone with a t-mobile sim I get a carrier an can the swap sims and still be unlocked
But only until next boot.
If I have any other card than the t-mobile sim in it while booting I get no carrier and am then locked completely not even t-mobile works.
I had to buy a pre-paid xtra-card during my trial and errors to activate the phone
That means I'll be paying t-mobile an annual unloccking fee a few Euros just to keep the t-mobile sim alive ;-))
Hope this helps somewith the no carrier problem.

I did the redsn0w iPad BB install on 4.1 but is it now impossible to upgrade to 4.2.1? If its possible, how would that be done since I can't use official firmware now that my BB is sky high?

I have baseband 05.13.04 on FW 4.1 (safe), is there a way I can update to 4.2 but preserve my baseband so I can unlock without using the iPad firmware?

I have 3GS newer bootrom previously on 05.14.02.. Did not touch 4.2 at all.. (I don't want to be tethered) I used redsnow and jailbroke to stock 4.1FW (what the phone was running before unlock)
All is good used redsnow to jailbreak & got to remain on 4.1 untethered. BB upgraded to 06.15.00 (most likely permanently) so I was able to run ultrasnow 1.2 and finally support my TMobile service on phone. Not too happy about GPS being all cracked out on me but everything that has presented itself as an issue so far I've performed the procedures the Dev team have dished out and so far the battery drain GONE, the activated sim GONE taken care of with SAM. anyway I'm sure the gps is next on list.. Thanks DEV TEAM!!
Just thought I'd give a testimonial
