Sorry, I had posted this, then found your earlier link, but the post was still being approved while my membership was approved.
Could you link me or maybe explain how to install the App Store back on the device if it is even indeed supported? Would you even recommend running Non-sse 4.4 over 4.0? I am not sure what is up with my appstore in 4.0, but it just keeps going to a blank page after I start installing a few apps on my account, then telling me I need to login no matter how many times I delete/readd/ or attempt to sign in on the account.
