First install ifile or ssh into your device. Navigate into /applications/preferences/ and youll find the file WYWAAppDetail.plist. Then find the string "setItemsPerApp" and then youll see "validTitles" under that as a key. In that add the title like "infinity_ITEMS" but it can be anything. Then you'l fond under validTitles "validValues" and put "-1" as a integer. And then go into settings and select the new option. Have your friends send you 11 text or something and you'll see it works
