@Phyurix

there are some small step u have to follow.

1st. ur time must not in auto set. set it manually.
2nd.  not sure region is important but i make sure all is in english united state n united state.
3rd. please install zune with the "102/103mb" version in offline mode(not connected to internet). google zunepackage-x86 102mb then u will get ur installer.
4th. please make sure u install the cert. my experience, i downloaded two cert from two different place. only one can get me unlock but not the other. if u fail to unlock please try another cert.

yes u still need to follow the major steps like free up https, install .netframework 4.0( what evilpuppy mentioned)
wish u good luck

well, try it on fresh clean pc Guarenteee work! if waiting M$ releasing custom ringtone support will be around August.

try to slim down your mailbox. hopefully below 50. delete it from inbox and trash bin as well.

first i need to know.

you sync ya email using wifi or data connection? both connection face the same error msg when u sync?

what kinda email? exchange or webmail?

if u connect to wifi, are your connection behind a firewall? you are using wifi connection from home or office?

is this hotmail your main account? if not can you delete the account and add back again?

if that's your main. U can't remove it. All u can do is select un-sync email. Then sync the whole acc again. If still happen. I strongly suspect 1 or few of your contact have problem.

if contacts have problem. Export it out as CSV format and check it 1 by 1.

after that delete all your contacts in hotmail. Then import the good copy of CSV files back to your contact.

nope.. there is no link to guide you thru this. this is all base on my experiences which i manage to fix my wife's hotmail contact in her mozart and my HD7 as well.

afraid this is the only way you can do it.

but again. if you un-sync your email the error code doesnt appear. it mean that not the problem on your contact. its the email in your mail which caused the error.

advise you delete all email and sync back.

the only way i did for friend of mine at NZ was thru Live messenger remote desktop. but again... i am working now... and might take some delay. so better make sure u are free for the next 2-4 hrs.

i cannot apply debit card on my xbox account..it says:
