The hebdev hebrew for 2.2 only was re-released by one of the ex-group members. The source url is
src.ph1.co.il . That same member promised to release the source code so the community can update it as open source to 2.2.1.
There are two forums where you can obtain updates, but you need to know Hebrew for that... One is
iphones.co.il and one is
ph1.co.il. The first one is owned by the guys that release the commercial Hebrew package and they sometimes censor threads that mention the free alternative (amazing that they think they can achieve something with that approach other than dissent). The other forum is owned by the same ex-member that just re-released the cydia source.
