ip4 - lost network after upgrade to 4.3.2
 

Good afternoon all, Ive got myself into a nasty litle situation.
i have an iphone 4, on three network in the UK, i was previously on IOS 4.2.1 but thought let me upgrade to 4.3.2. now i have no network ?? i used the latest r14 version of redsnow as i only wanted the jailbreak as thinking my phone doesnt need unlocking as im using the same sim card as before. I really dont know how to fix this problem and its stressing me out to say the least as i have no other phone.
if anyone can help it would be so so appreciated

use this tutorial friend you will solve it. How to Jailbreak iPhone 4.3.1 with RedSn0w [Tutorial] » Unlock iPhone first upgrade

No problem, just deactivate and activate in itunes, after you restored, you activated by jialbreak without activating with itunes. Very important. Make restore again and activate before you jailbreak, after restore just put sim card and connect to itunes, menu will be open b4 you make jailbreak


or as it is now

open cydia

add this source

repo.bingner.com

install sam

open sam and click revert lock down

click restore activation

insert sim

connect to itunes

all will be ok

I have same problem. I tried everithing this but always Lost network... Its strange. I make manual search and the phone show all networks, but when i chose my network give Lost network.... My pphone is factory unlocked... I think is hardware problem
