Sat May 25 2002 14:59:43 Hong Kong Time - XBox
Our first limited supply of Xtender Xbox modchips came in this morning and have been dispatched to those customers who made their reservation on its first preorder day. If you are among the lucky ones, you will receive a shipping confirmation e-mail shortly. More chips will come in early next week and will cover all current preorders that are placed before the end of this week. Sufficient supply should then finally become available around end of next week.
The Xtender modchip is the first worldwide available modchip for the Xbox. It plays back all import and backups on all worldwide sold Xbox machines.
