The other way is by using data cable, either serial or usb. Make sure you get the compatible one for your X426. Compatible models include:
D410-D418 / E300 / E310 / E600 / E710 / E715 / E850 / P100 / P400-P408 / S300-S307-S308 / V200-V206 / E600-E608 / X475 / X480 / E610
E105 / E315 / E316 / E317 / E715 / S307 / V205 / V206-P107 / X105 / X426-X427 / D415 / X475
If you get the usb one, you need to install a driver. You don't need a driver if it is serial one. For Serial cable, its P/N is PCB093LBE.
For where to get the cable, either go to the cellphone accessories shop or if you want to get it online, do a google search for X426 data cable.
When you have the cable, download SGH-X426 PC Studio PIMS (ver.1.0) from Samsung:
