Okay first you need to verify all of your account information in paypal including: * Your phone number * Your Address * Your Payment information Once you are all verified and you are still getting this 601 error the problem is most likely due to one of two things or possibly both: 1) You have not used your account in a long time 2) Your account was compromised at some time in the past At this point you will need to contact paypal support and have them do their voodoo. A few clicks later on their side they will tell you to either clear the internet cache (temp files) on your broswer or restart your mobile device if that is what you are trying to use. After I did all of that I was able to successfully purchase from the ebay app on my mobile that is linked to my paypal without the 601 error. Hope this helps!
