You guys are playing with yourselves.
Its no secret that googles checksum algorithym fpr pr was cracked and there are many cracked versions floating around but apart from minor variations on different data centers you wont see squat difference.
And your cracked versions wont work for too much longer as Google have changed their algorithm for the toolbar just a few days ago and are currently updating everyones toolbar.
The cracking of their checksum algorithm could be the reason why they have taken so longer to do a pr update.
