I sent my iPhone to a repair shop because my Wi-Fi chip was broken on my iPhone 4?

I was wondering if apple or another phone repair shop could repair the Wi-Fi chip on my iPhone 4

Apple can repair anything i guess since iphone belongs to apple. If you have insurance for your phone it will be free cost but if you don't, it may be just a bit to pay.

If you r still under warrenty you can repair free of cost on Apple store.Local repair shops might be able too by changing Wi-Fi chip, drying cooling etc but may charge u a bit more. Hope your iphone Wi-Fi would be fine after repair
