GSM version should work, not sure about the CDMA one though.

did u unlocked it here,  I tried unlocking but they were not successfull about a month ago..may be they can now with relese of new hack from xdadevelopers..

Same discussion is here..

yeah of course it does.. after u unlock n unlocking is pretty simple if u do not have the latest firmware updated.. n even in Nepal, u could unlock it for Rs 500-1000. There too many places in Nepal, u cud do on ur own if u have Internet connection available like a wifi or a 3G.
My $0.02

Just a quick reply for this post..

answer is it will work..

but i think the firmware it use now i guess is 4.2.1 and firmware is the latest..

you can jailbreak it with the IPAD firmware that will be 6.15.00

now here is the problem.. it will work just fine..

but when you get the message and try to view it.. the springboard will crash..

but you can do it by closing the instant message and go to homescreen and opening it.. it works good but more step to follow..

you cannot use the multitasking.. if you do it.. springboard crashes as well..

some of the apps don';t work good if it needs 4.2 just like HITSFM for me.. it just shuts down on the jailbroken iphone..

it has lot of problem.. but for me i can make the adjustment.. I don't know about you guys.. and if you are thinking about verizon which might use CDMA.. then i think it will be useless.. But i am not sure they have dual CDMA/SIM system same as blackberry storm 2..

Choice is yours.. Iphone 4 can be jailbroken and used in nepal.. but consider the drawback until there is the update in the jailbreaking procedure..

and about the smaller simcard.. you can get the sim card trimmer on Ebay..

If the I-phone 4 is Unlocked Mobile phone it will work in any GSM Network Sim card in Nepal...If the I-Phone 4 is locked means it will not work in NEPAL or any GSM Network Sim card....To Know it's locked or unlocked just insert other GSM Network Sim card.IT accept means it's unlocked phone...It's locked means it says invalid sim or enter unlock code or unlock it message..So you need to unlock it..You can get the Remote I-Phone 4 unlocking service from here Theunlockspot.com/apple-iphone-4/rs10wp9/ and Unlock it.
