There are new firmwares for Ideos S7 on Huawei website.
i didn't download the files to see build prop, but from firmware numbering, i assume these are froyo firmware.
some of them are android 2.2.2 and some are 2.2.1
if someone downloaded and found these are firmware, i will move the link to eclair firmware thread.
S7V100R001C13B115 (Australian Telstra)
