I searched Sanyo's support website and see nothing - Only thing I can suggest is email support on Sanyo mobile device website.
Despite the claims by several vendors, there is NOT a driver available for this phone. I returned mine before the 30-day period and exchanged it for a better phone with an SD card, wireless backup for Contacts and excellent photos---->LG Rumor Touch. I paid $25 for restocking....but well worth the money because the LG does everything. In my opinion, the Vero is only good for making/receiving calls and texting. If you need more, buy something else.
