The purple tint is fine. It is not burnt. Since your plant has purple flowers that is probably why the leaves are purple. Dark colored flowered Phals can have purple leaves. It can also be a sign of high light. If it is from light it won't hurt the plant but make sure it doesn't get much higher light cause it can burn. Burns won't usually kill the plant but it is unsightly. Here is a link to pics of leaf burn.

Don't water your plant with ice cubes. It is only a marketing gimmick to sell orchids. The company of these Ice Cube Orchids want the plant to seem way easy to take care of, only requiring three ice cubes a week so people buy them. If you melt 3 ice cubes that is not much water. They need a lot more water than that. When the plant is dry put it under the sink and water it really well with water close to room temp. Make sure it isn't too cold. Remember these are tropical plants and don't receive snow or ice in nature. After watering the plant well, let the pot drain well. If the plant is in a decorative pot, take the plant out of that pot (it should be planted in a plastic pot and might be put inside a decorative pot) to water. You don't want water sitting in the bottom of the decorative pot.
There is really no way of telling you how often to water. It depends on your growing conditions. So you might have to water once a week or more or less than that. Many members use a wooden kabob skewer to gage when to water. Put one in the middle of the pot since that is where the medium dries out last. You want to keep the skewer in the pot at all times. Pull it out to check if the plant is dry. If it is wet it is not time to water. If it is dry then water. If you are not sure if it is dry enough, wait one more day and then water. This works really well and takes the guess work out of watering. Don't let the plant go dry for to long though.
What is the plant potted in? Bark, moss? I would check the roots. Many orchids bought in grocery stores are potted in tightly packed moss and this can cause root rot. You might need to repot the plant to avoid root rot. You do not want root rot! It is hard to get the plant to recover from that. Phals usually do really well being repotted even in bloom. Sometimes if you wait for the plant to go out of bloom to repot it may be too late.
Welcome to Orchid Board!
If you have more questions don't hesitate to ask! There is a great thread called the Phal Abuse Ends Here and it is packed full of great information on caring for Phalaenopsis orchids bought in grocery stores and big box stores and Phals in general. Here is the link.

P.S.- I don't see a pic of a curled leaf. If you are concerned about it post a good pic of it. Phals do shed their bottom leaves at some point then they grow more from the top.
