Can someone please help me with updating my DSi in addition to my r4i gold?!?!

I have a Nintendo US DSi and i want to update it but i don't know if my r4i gold will still work. This is the website to update my r4i gold- http://www.r4ids.com/r4i-download-e.html and i have the latest version v1.31 i think. Can someone also please tell me what version the DSi is able to update to because i think I'm on version 1.3.

Previously said in the website, cards released before Aug 2009 have problems on 1.4 firmware. If yours is released after that, it should work fine (mine is ok).

^ Yup.To update your DSi, you need to have Wi-Fi access. Connect to wifi, go into shop channel, and do a system update.
