iphone 3GS restore

[tcouto]

Hi everyone.... been reading a lot these days about jailbreaking, but still havent found a definite answer to my problem.

I bought a used iphone 3GS jailbreaked and unlocked running 4.1 (done by the previous owner). Baseband is 6.15 and it has the old bootrom.

My goal is to perform a clean install to 4.1. Here is what I learned so far. If it is in the ipad baseband I have to use a custom firmware. But which firmware will I use in PwnageTool? Do I need SHSH for 4.1 (i don't have it apparently).

If I cant use 4.1 can i clean restore to something else. Im kinda lost here!

Thanks

This video should explain what you have to do.

You will most likely get a 1015 error after the restore. Just download iReb and use it and all will be solved.

Thank you for your response.

I followed these instructions:

Humm... dont seem to be able to send mms in 4.2.1. When running 4.1 that wasnt an issue!!

Has anyone read anything about this?

I have no issue with MMS on this. So, if you are on T-Mobile, then try this;

1. Open Cydia.
2. Manage/source/edit/add
Cydia.pushfix.info

Add source.

3. pushfix.info/T-Mobile US MMS fix

Then,
4. Setting/general/network/cellular Data network/MMS:

APN: wap.voicestream.com
Username:
Password:
MMSC: 216.155.174.84/servlets/mms
MMS Proxy 216.155.165.50:8080
MMS Max Message size:
MMS UA Prof URL:

Thanx, but I'm on a Portuguese network! Some O2 users said the issue was related to MMS size... but I have no options regarding that parameter!

A bit more of research really points out the message size being the problem. Something to do with 4.2.1 not resizing pictures automatically. Now trying to figure out a solution for this...
