Unless you have iOS 5.1.1 blobs saved with valid APTickets back when iOS 5.1.1 was being signed, or any iOS blobs with valid APTickets, the only iOS you can restore to is the latest, which is 6.1.3

If you upgrade your pone to 6.1.3, you will no longer be able to use UltraSn0w unless you're on the old baseband 3GS.

And Friend when i open Cydia in my Iphone 3gs it shows (shsh: 4.1, 5.1.1)what it's mean?

Read up about SHSH blobs here, which are what you see in terms of numbers listed above.

UltraSn0w requires either 05.13.04 or below, or the flashed iPad Baseband. Depending on whether your device is a new or old bootrom 3GS, there are 2 different ways of flashing the iPad Baseband, the easier being the old bootrom, the lengthier being the new bootrom.

Since 5.1.1 is listed, and assuming it has valid APTickets alongside with it, you can restore to 5.1.1 using RedSn0w, or restore + jailbreak using Sn0wBreeze's custom IPSW method.
