Notcom has now added Verizon iPhone 4 support to TinyUmbrella tool. The TinyUmbrella 4.21.08 will help you save SHSH blobs on the iOS 4.2.6 based CDMA iPhone, which will be available for end users on February 10, 2011.
Since the phone is not officially available for most of the Verizon users, TinyUmbrella 4.21.08 is a beta release and you may find bugs or errors in this tool.
The official update -
TinyUmbrella has been updated to support iPhone 4 CDMA aka Verizon. Note that since I do not have a Verizon iPhone 4, support is BETA. Please don’t be surprised if I need to post another update with findings that are sure to come… Enjoy!
