This is for some users with earlier version of J2ME runner (before 1.2). Actually, this is caused by another bug of android installer system. The reason is our version 1.2 uses a different signature then previous one. But the Android updater was not able to handle it cleanly C it tried to update but failed to uninstall the previous version cleanly and rendering some old data hanging around the system. To overcome it, what you need to do is to use an old version of package with old signature, and then perform the following steps: • re-install old version of package • uninstall old version of package Now you can install the new versions. Of course, an alternative is to perform a factory -reset your G1. J If you have questions, please do not hesitate to contact us and we will happily to provide you access to the old packages.
