Could anyone help check FOR mistakes please? Thanks a lot! When I HAD just graduated from college, my older sister bought me a new phone, which WAS my first smartphone, and it cost her A month'S salary. I used the phone for the first few days and one night, on the way to my dorm, I put my phone into my pocket and a guy walked quickly past me. After A minute, I reached into my pocket AS I wanted to send a message, but my phone was MISSING. I realized the guy WHO HAD just pasSED me had pickpocketed it. I ran AHEAD quickly, but could not find the pickpocket. I was so sad, since it was a new phone and it cost a lot. I cried that night and dreamt of finding it. 你好 Sophia. Not too bad. Notice that "one" is generally just for numbers. Imagine you say, "I've got one friend." Only one? Also, unless you are sending a text message, in writing it is better to write the word for numbers. Just a suggestion - italki gives you the option to do this as a Question, Exercise, or Post. The Post is designed for teachers to be able to correct it more easily and you can see the changes in blue. Keep practicing!

Your paragraph is mostly clear, but there are a few minor mistakes. Here's a corrected version: "When I had just graduated from college, my older sister bought me a new phone, which was my first smartphone, and it cost her one month of salary. I used the phone for the first few days, and one night when I was on the way to my dorm, I put my phone into my pocket, and a guy walked quickly past me. After 1 minute, I reached into my pocket and wanted to send a message, but my phone was lost. I realized the guy who had just passed me had pickpocketed it. I ran up quickly but could not find the pickpocket. I was so sad since it was a new phone and it cost a lot. I cried that night and dreamt of finding it."
