How to sign an IPA file with 3utools
3utools is one of the best iOS tools for Windows, and one of its cool features is that which allows you to sign IPA files. Here, we will walk you via the steps on how to sign an unsigned IPA file using 3uools. 

This process will come handy especially if you are a developer and have just developed an iOS App which isn't available on the Apple Store and will want to test it. 

You can normally sign an IPA file using a developer certificate or an Apple ID and install on your iDevice. 3utools lets you sign IPA files pretty easily. So, you can either purchase a certificate and use 3utools to sign your IPA file or sign in with your Apple ID.

It should be noted that IPA files signed with an Apple ID will need to be resigned after 7 days (Cert will expire after 7 days). But with a self-purchased certificate, you can do the resigning after a year.
