Hi guys, usb port solder is a good practice, but not prevent wear resulting from usage, I try this http://www.banggood.com/Magnetic-Ads...p-1004685.html Magnetic Adsorption Micro USB Universal Charger Cable and it work great, this protect the micro usb port in n900 from wearing for repetitive use.
charging and data transfer work as normal usb cable, one piece is attached to usb port an connect and disconnect is made via magnetic attraction thus prevent stress and wearing in the phone usb port ¡¡¡ CAUTION !!! File down the USB cable's hooks as described by dr_frost_dk http://talk.maemo.org/showpost.php?p...61&postcount=2 at begin of this post
The metallic piece that still attached to the phone have very tight fit,if the hooks are not well smooth with a file is very hard to remove later without damage the n900 usb port
¡¡ you are advised !!
instead of the filed hooks I use small pieces of double sided tape to mantain male usb united to n900.
I use OtterBox case in my phone with wrist strap
