We have mentioned Cheservices a few times as a good source for OTA Hebrew input files but SLS let us know about a similar project he is working on. He setup www.slsapps.com that has the OTA Hebrew language files for quite a few devices ranging from OS 4.5 to 7.1. Let us know if it works for your device!
Check it out at www.slsapps.com
PS: This is for all of you who have been asking me every day for Hebrew language files
